Some fiat entered. It will probably be around Wednesday when the dumping continues. Till then, the dumpers are waiting if maybe more fiat will be wired, so they can sell with an better price.
I'm not buying into this because it isn't very probable that much more fiat will enter. There hasn't been any important good news about the markets, so nothing has really changed in the long-term.
It's Monday so could it be that people are waiting for their deposits to hit the exchanges? You know, the deposits they wired when they saw cheap bitcoins at 400 yesterday. And what will these people do Tue/Wed when the fiat is there? BUY!
Just my guess.
